William Rotsler (1926–1997)

A little hard to say what to make of these - they are indeed Star Trek short stories, and they are not terribly Star Trek III themed, apart from some of them being vaguely set around that time and none of them being focused primarily on Spock. There's a variety of non-canonical oddnesses in them (some term for a medical tricorder, for instance, that isn't really in use anywhere else in the show).

Rather old fashioned stories about each of the crew members that reminded me of pulp novels. Some, like one that visits an underground society, felt almost like L. Frank Baum or something of that era. Not...notably good, shall we say.

This book is weirder than I had initially imagined it to be. It's basically dossiers of each of the characters, and none too canon-compliant either (apparently Sulu is Hawaiian? And "Zefrem" Cochrane and "Noyota" Uhura? LOL). It's also incredibly poorly proof-read. It DOES address, however, the major hole that Khan never met Chekov before the events of STII, and I found it fun to read despite everything.

Full of quotes from SF authors of all stripes. Great fun.
